2-1. FEATURES Anti Crease function With the alternate rotation of the drum, creasing in the laundry is minimized. More economical by Fuzzy Logic System FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption. Child-Lock The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation. Low noise speed control system By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level. Direct Drive System The advanced Brushless DC motor rotates the drum directly without a belt and a pulley. Built-in heater Internal heater automatically heats the water to the best temperature on selected cycles. 4 2.FEATURES & TECHNICAL EXPLANATION

5 2-2. DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount. 2-3. WATER LEVEL CONTROL This model uses a pressure sensor to determine the water level in the tub. When the preset water level reached, water supply is stopped and the program proceeds. W ater needs to be below a preset level before spining will proceed. water temperature washing time rinse time the best washing performance spin rhythm, time laundry amount FUZZY LOGIC selected washing temperature SENSING EFFECT PROCESSING DETERMINATION 2-4.

7 4.INSTALLATION INSTALLATION The appliance should be installed as follows. Check the conditions of installation area. 1. Check level ground. On raised foundations or upper level homes, the vibrations can be caused by the type of flooring. It may be necessary to move the machine to a different area in the home or have the floor reinforced to properly support the operation of the unit. 2. Check humidity or any foreign objects under the feet. Clean the floor, and there should not be any foreign objects under the feet. If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly and will cause vibrations and slipping . Remove any foreign objects , if any from underneath the machine and level unit properly. See below for examples of foreign objects. 1 Open the box and check appliance condition. 2 horizontal Capet Paper Laminated paper Washer Base Packing Wrench This leveling (or spanner) wrench must be used to remove the shipping bolts and level the unit. This should be kept for future use. Packing Support Purchased stopper

8 Use spanner to remove transit bolts. 3 Confirm the distance between the appliance and the wall. 4 The tap connection and hose connection must be parallel. 5 Without removal of transit bolts Spin noise and shaking . X 4 EA Transit bolts More than 2cm If the distance is less than 2cm, the water supply hose will kink or fold . 1. Normal Tap without thread & screw type inlet hose. 1. Unscrew the fixing screw to attach the tap. 2. Push the connector up till the rubber packing is in tight contact with the tap. Then tighten the 4 screws. 3. Push the water supply hose vertically upwards so that the rubber packing within in the hose can adhere completely to the tap and then tighten it by screwing it to the right. 1. Untighten the upper connector screw. 2. Push the upper connector up till the rubber packing is in tight contact with the tap. Then tighten the 4 screws. 3. Connect the water supply hose to the middle connector, pushing the plate down. • In case the diameter of the tap is large remove the guide plate. • Turn the middle connector not to have water leaked. • Make sure that the rubber seal is inside the hose connector. • To separate the water supply hose from the middle connector shut off the tap. Then pull the inlet hose down, pushing the plate down. • Make sure that there are no kinks in the hose and that it is not crushed. 2.

9 Connect Drain Hose. 6 Connect power plug. 7 If the drain hose is not installed properly, the unit will not drain properly. This allows water to back flow into the unit which can cause odors. Refer to Owner Manual for proper drain hose installation. The odor could also be coming from the home’s drain to which the drain hose is attached. In this type of drain hose installation, the odor could be coming from the standpipe. This odor can come up the drain hose and into the unit. Pour a cup or two of bleach or vinegar down the home drain and let it sit for 24 hours before running another cycle. This will help eliminate odor from the home drain. If a cycle is started too soon after doing this, it will not help the issue. Connect the power plug to the wall outlet. Avoid connecting several electric devices, it may be the cause of a fire. about 100 cm about 145 cm about 105 cm Laundry tub Max. 100cm min. 60cm Max. 100cm min. 60cm Retainer Tie strap Hose min. 60 cm max. 100 cm
